Chrysanthemum plant named ‘Zanmuceles’

ABSTRACT

A  chrysanthemum  plant named ‘Zanmuceles’ characterized by its medium sized blooms with white ray florets and prolific branching; natural season flowering date September 9-13 (week 37); blooming for a period of 5 weeks.

Botanical designation: Chrysanthemum×morifolium Ramat.

Cultivar denomination: ‘Zanmuceles’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of chrysanthemum plant, botanically known as Chrysanthemum×morifolium Ramat., commercially known as a garden mum, and hereinafter referred to by the cultivar denomination ‘Zanmuceles’. ‘Zanmuceles’ is a product of a breeding and selection program for outdoor pot mums (garden mums) which had the objective of creating new cultivars with a double type inflorescence, a natural season flowering date around week 37, blooming for a period of 5 weeks. ‘Zanmuceles’ is a seedling resulting from a cross of the female parent id 30549 (not patented) with the male parent id 26356 (not patented). Plants of the new cultivar ‘Zanmuceles’ differ from plants of its parent plants in growth habit. The female parent has a more compact shape than the seedling, while the male parent is more spreading than the seedling.

The new and distinct cultivar was discovered and selected as a flowering plant by Henricus Cornelius Maria Jacobs on a cultivated field in Rijsenhout, The Netherlands in 2010. The first act of asexual production of ‘Zanmuceles’ was accomplished when vegetative cuttings from the initial selection in 2010 were propagated further in a controlled environment in Rijsenhout, The Netherlands. In summer, about 6-8 days are needed to initiate roots in cuttings of the new cultivar, after another 5 days rooted plants are formed. The new cultivar has been found to retain its distinctive characteristics through successive propagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum (of about 12 weeks) is shown in the accompanying drawings, the color being as nearly true as possible with color photographs of this type.

FIG. 1 shows a plant of the cultivar in full bloom.

FIG. 2 shows the various stages of bloom of the new cultivar.

FIG. 3 shows the various stages of foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

The observations and measurements were gathered from plants, in the period of 11 to 18 weeks of age, grown outdoor in Rijsenhout, The Netherlands under natural day length and temperature and planted in week 23 in 2013 (with a warm summer), receiving drip irrigation. The natural blooming date of this crop was September 9-13 (week 37). The average height of the plants was 40-45 cm. No growth retardants were used. No tests were done on disease or insect resistance or susceptibility. No tests were done on cold or drought tolerance. This new variety produces medium sized blooms with white ray florets blooming for a period of 5 weeks.

From the cultivars known to the inventor the most similar existing cultivar in comparison to ‘Zanmuceles’ is ‘Crete’ (U.S. Plant Pat. No. 16,677). When ‘Crete’ and ‘Zanmuceles’ are being compared the following difference is noticed: The difference of ‘Crete’ and ‘Zanmuceles’ are (1) Inflorescence size. And (2) Inflorescence color. (1). Inflorescences of ‘Crete’ are smaller than those of ‘Zanmuceles’. (2) The inflorescences of ‘Crete’ are cream colored, while those of ‘Zanmuceles’ are pure white.

The following is a description of the plant and characteristics that distinguish ‘Zanmuceles’ as a new and distinct variety.

The color designations are taken from the plant itself. Accordingly, any discrepancies between the color designations and the colors depicted in the photographs are due to photographic tolerances. The color chart used in this description is: The Royal Horticultural Society Colour Chart, 5th edition 2007.
